I want to put a header back exhaust on, but as you know the catalytic converter outs attached to the stock header. How do you get rid of that and still pass emissions???

You get your emissions sticker first, then modify, but retain the stock setup to swap prior to the next inspection.

There are two cats, the pre cat in the header, and the actual cat in the middle of the exhaust. Losing the pre cat will not cause you to fail emissions unless your state does a visual.
